cause (one) qualms
To cause one to feel some or certain hesitations, apprehensions, uneasiness, or pangs of conscience (about something or someone). Lying always causes me qualms, so I doubt I'll be able to tell my boss that I'm sick just to get a long weekend. I thought Jonathan's promotion was a done deal, but his latest interview seems to have caused the board of directors some qualms. I know I said I'd go to the party tonight, but I'd have to sneak out, and that's causing me qualms.
